Data from in vitro and in vivo models suggest that malnutrition and stress trigger adaptive responses, leading to small for gestational age (SGA) blastocysts with fewer cell numbers. These stress responses are initially adaptive, but become maladaptive with increasing stress exposures. The common stress responses of the blastocyst-derived stem cells, pluripotent embryonic and multipotent placental trophoblast stem cells (ESCs and TSCs), are decreased growth and potency, and increased, imbalanced and irreversible differentiation...

Human luteinizing hormone (LH) and chorionic gonadotropin (hCG) have been considered biologically equivalent because of their structural similarities and their binding to the same receptor; the LH/CGR. However, accumulating evidence suggest that LH/CGR differentially responds to the two hormones triggering differential intracellular signaling and steroidogenesis. The mechanistic basis of such differential responses remains mostly unknown. Here, we compared the abilities of recombinant rhLH and rhCG to elicit cAMP, β-arrestin 2 activation, and steroidogenesis in HEK293 cells and mouse Leydig tumor cells (mLTC-1)...

INTRODUCTION: Endometriomas are present in up to 44% of all women with endometriosis and have a detrimental effect on fertility. However, it is controversial whether endometriomas should be surgically removed before assisted reproduction technology (ART). Our purpose was to evaluate whether surgical stripping of endometriomas in subfertile women improves the chance of a live birth. Secondary outcomes were impact on ovarian reserve and pain. Material and methods We conducted a systematic review and metaanalysis with results reported in accordance to the PRISMA guidelines...

Improvements in oocyte cryopreservation has prompted wider acceptance of this technology leading to its use for several reasons. Notably, in addition to elective and medically driven reasons for oocyte cryostorage for fertility preservation, donor oocyte cryobanking is beginning to gain traction, potentially replacing fresh oocyte donation in assisted reproduction. Donor "egg banking," while not totally analogous to donor sperm banking, does provide strong benefits in terms of scheduling flexibility and improved clinical efficiencies, while providing a wider immediate inventory choice...

The ability to store human embryos in a viable state at very low temperatures has been critical to the evolution of responsible practice in clinical Assisted Reproductive Technology (ART). It has encouraged a reduction in the frequency of simultaneous multiple embryo transfer and thereby reduced the risks associated with multiple pregnancy while maintaining high cumulative pregnancy rates from single oocyte collection cycles. In this chapter, we describe a simple slow freezing procedure for human early cleavage stage embryos that results in a high proportion of post-thaw embryos surviving and retaining their implantation potential...

Cryopreservation of human spermatozoa is a highly efficient procedure for managing male fertility, and much of its successful application seems to have a crucial impact on the reproductive outcome of assisted reproduction technologies. Here, we present, explain, and describe the slow freezing method for preserving human spermatozoa, which is currently the most commonly used freezing technique in most clinical andrology laboratories.

The placenta is vital to fetal growth and development, as it bridges the fetus and the mother. Genome-wide epigenetic regulations (e.g., DNA methylation, histone modifications, non-coding RNAs) participate in many aspects of placenta development, including decidua of the uterus, trophoblast cell adhesion and invasion, angiogenesis and placental imprinted gene expression. Environmental factors during pregnancy, such as heavy metals, chemical compounds, modern assisted reproductive technology and the nutrient conditions, may cause abnormal placental epigenetics...

So far data on the effect of assisted reproductive technologies (ART) on the components of first trimester combined screening for Down syndrome are still controversial. A systematic search of the literature was performed in order to identify the effect of ART, particularly IVF and ICSI with fresh embryo transfer, on the nuchal translucency (NT), free β-hCG and PAPP-A measurements. Moreover, a meta-analysis and a descriptive graphical representation of the ratios between ART and spontaneous pregnancies (controls) values of median of the multiple of median (m0MOM) was performed...

Approximately 1-4% of children today are conceived using assisted reproductive technologies (ARTs), including in vitro fertilization (IVF). IVF is considered safe and the great majority of these children are healthy, yet there is increasing physiological and molecular evidence from animal models that ART is associated with postnatal metabolic and cardiovascular alterations. Understanding the mechanisms underlying these changes and determining whether they have biological significance is of paramount importance for optimizing the design of culture conditions and improving the health of ART children across the life course...

Concerns have been raised about the health and development of children conceived by assisted reproductive technologies (ART) since 1978. Controversially, ART has been linked with adverse obstetric and perinatal outcomes, an increased risk of birth defects, cancers, and growth and development disorders. Emerging evidence suggests that ART treatment may also predispose individuals to an increased risk of chronic ageing related diseases such as obesity, type 2 diabetes and cardiovascular disease. This review will summarize the available evidence on the short-term and long-term health outcomes of ART singletons, as multiple pregnancies after multiple embryos transfer, are associated with low birth weight and preterm delivery, which can separately increase risk of adverse postnatal outcomes, and impact long-term health...

Oocyte cryopreservation is imperative for assisted reproductive technologies (ART). Although cryopreservation of oocytes at the Metaphase II has been widely used, immature oocytes at the germinal vesicle stage (GV-oocytes) need to be cryopreserved in certain situations such as cancer patients; however, the success rate of embryonic development from the GV-oocytes remains low largely due to the requirement for in vitro maturation (IVM). Our aim was to investigate the effects of glutathione (GSH) supplementation during vitrification and warming of mouse GV-oocytes on the preservation of developmental competence...

PURPOSE OF REVIEW: Due to the fact that the Zika virus can be sexually transmitted, there is a potential risk for disease transmission at several stages of assisted reproduction. Such a possibility poses a serious challenge to couples pursing fertility with reproductive technologies. Here, we discuss what is known regarding Zika virus infection with respect to sexual transmission and correlate this knowledge with recent recommendations in the realm of infertility treatment. RECENT FINDINGS: Zika virus can be transmitted from infected men and women through vaginal, oral or anal intercourse...

A large number of human diseases arise as a result of genetic abnormalities. With the advent of improved molecular biology techniques, the genetic etiology of male infertility is increasing. The common genetic factors responsible for male infertility are chromosomal abnormalities, Yq microdeletion and cystic fibrosis. These are responsible for approximately 30 percent cases of male infertility. About 40 percent cases of male infertility are categorized as idiopathic. These cases may be associated with genetic and genomic abnormalities...

Oncofertility is a unique, multidisciplinary field that serves to bridge the gap between available fertility resources and the special reproductive needs of cancer patients. Oncofertility is a growing field due to the increasing number of survivors, development of new oncologic therapies, extension of duration of therapies, and development and refinement of reproductive therapies. While the technologies and demand for services expand, clinicians need to be appropriately prepared for dealing with various clinical scenarios that may require ethical deliberation...

PURPOSE: The study aims to describe two promising therapeutic options for resistant "thin" endometrium in fertility treatment: granulocyte colony-stimulating factor (G-CSF) and stem cell therapy. METHODS: A review of the scientific literature related to patients with thin endometrium undergoing fertility treatment. RESULTS: Sufficient endometrial growth is fundamental for embryo implantation. Whether idiopathic or resulting from an underlying pathology, a thin endometrium of <7 mm is associated with lower probability of pregnancy; however, no specific thickness excludes the occurrence of pregnancy...

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is the most serious complication of controlled ovarian stimulation (COH) during assisted reproductive technology (ART) protocols. This syndrome is a result of ovarian expression of vascular endothelial growth factor (VEGF), which increases vascular permeability. OBJECTIVES: To evaluate the efficiency of prophylactic and therapeutic use of cabergoline in women with higher risk of developing OHSS. MATERIALS AND METHODS: In this prospective randomized study, 146 women undergoing in vitro fertilization (IVF) cycles with GnRH agonist protocols with a higher risk of OHSS diagnosed during the HCG day administration (more than 18 follicles observed larger than 12mm in diameter during COH and/or estradiol levels of 3000-3500pg/ml, previous episodes of OHSS)...

Sociocultural meanings accorded to infertility, and rapid developments in assisted reproductive technologies, have long been central concerns in feminist and social scientific research. However, knowledge is scarce concerning how individuals make sense of infertility when it is disclosed in adolescence, for example as the result of an 'atypical' sex development, rather than as a result of failed conception. This article examines how understandings of desires, kinship and 'solutions' take shape and are negotiated in the accounts women give of infertility resulting from 'atypical' sex development...

The management of pregnant women who are themselves affected with genetic diseases is an increasingly relevant and important issue. Improvements in early diagnosis and management of genetic disease, as well as advances in assisted reproductive technology have impacted pregnancy rates in a cohort of women who may not have otherwise been able to conceive. A multidisciplinary approach is key to the management of pregnant women with complex health conditions, including genetic diseases. Pertinent issues should be addressed in the preconception, antepartum, intrapartum and postpartum periods to optimize maternal and fetal health...
